that seems amazingly high to me. I don't have much sense for rent,
but even if we ran our clusters on "retail" power rates it would only
amount to 2.3% of purchase cost. you could pretty easily argue that
our purchase prices are high, but even so still < 10%/year. with your
kind of costs, wouldn't it make sense to consider a colo site? from
a cursory grep of the web, it sounds like they're still substantially
less than 33%...
